I personally believe that time travel will become a reality in the near future, but think about it. Do you really think mankind is mature enough and ready for it? Time travel will bring up many, many questions on morality when it becomes possible. I am not worried about it ever becoming real, that is inevitable, I am worried about how people will use it. Will time travel be restricted only for emergencies? Will any normal, average person be able to use it whenever they want, for whatever they want? Will only a select few people (scientists) be able to use it? These are the things that I am worried about.
